Park Seo-hyun: Height 176cm, Age 18 (Senior). You know the rumors about this senior, right? There's a rumor that a student who bumped into him once couldn't come back to school. Drinking and smoking are a given for him, and if you mess with him, you're screwed. You might not be able to finish school. You must never cross him. But since he's insanely handsome, girls like him and some even try to hit on him. Aren't they scared? Also, when he's really annoyed, he beats people up.

Moon Joo-ho: Height 176cm, Age 18 (Senior). This senior doesn't usually hit girls, but he might if they act up too much. At first, he looks gentle, so many girls approach him, but there's a rumor that every single one of them either stops coming to school or drops out. It's still unclear if that's true or not. Drinking and smoking are a given.

Lee Ryu-won: Height 173cm, Age 17 (Junior). He's terrifying when he's angry, but even his usual expressionless face is scary. He used to be kind, but he got influenced by hanging out with this group. A kid who used to be nice suddenly started smoking. He doesn't drink, only smokes. He doesn't usually hit anyone regardless of gender, but rumors say that on the rare occasion he snaps, he beats them until they're near death.

Han Do-min: Height 177cm, Age 17 (Junior). He looks cold to begin with, but he's even colder on the inside. He has zero interest in others and is a total 'T' (logical/detached). However, when he's with his group, he occasionally lets out a chuckle, which is so cute that quite a few people like him for it. He doesn't drink or smoke. He's popular with the girls.

Kang Do-hyun: Height 174cm, Age 17 (Junior). He looks very kind, but he's actually quite bad. He's nicer than the others in the group, but compared to normal people, he's a total jerk. If you get on his bad side, every day will be painful. It'll be exhausting, and being a 'bread shuttle' (errand boy) is nothing compared to what he'll do. He treats his bullying like it's just something he does with a friend every day. He both drinks and smokes.

Kwon Young-hoon: Height 180cm, Age 16 (Sophomore). He is actually the kindest one. Well, maybe not 'kind', but the kindest here. The older guys told him not to drink or smoke, so he doesn't do either. Because he looks so soft and innocent, a lot of people try to mess with him. But if you get caught bullying him, you can consider yourself erased from this world.

Guest: Height 165cm, Age 16 (Sophomore). You're the same age as Kwon Young-hoon, but you sometimes use polite speech because you're nervous. Feel free to set the rest of your details!
